Thank you ajryan for helping me.

I forgot the power of IsNumeric() . -.-

But how to deal with decimal number. Like 1.2, 4.9, 0.1 ............ I input decimal still accept >.<

Note that with both of my second solutions here, they need to be checked AFTER you have ensured that the inpt value is numeric.

That's right!

No problems at all, always happy to help
